ABSTRACT:
A flexible electrical contact is formed as a convex dome structure extending from one side of a surrounding structure, with the convex dome structure and the surrounding structure forming an integral metallic structure. The convex dome structure includes a central contact portion and a number of legs extending between the central contact portion and the surrounding structure. Each leg extends radially outward from the central contact portion and circumferentially around part of the central contact portion. A number of convex dome structures of this kind may be part of a removable shield in an electronic enclosure, provided to electrically ground the shield to a conductive frame, reducing the level of RFI (radio frequency interference) emissions from a device. Alternately, a number of convex dome structures may be provided along spring strips fastened to such a shield. In such spring strips, electrical contact may occur between the shield and intermediate positions along the length of the legs.
